.SPEEDER FOR BICYCLES.

SECIFICATION formng part of Letters Patent No. 629,032, dated July 18, E1899.

Application filed May 31, 1898.

T0 all whom it may conccrn: v

Be it known that I, WILLIAM READING GULICK, a citizen of the United States, resi1 ing at Bay Head, in the county of Ocean and State of New Jersey, have invented certain new and useful Improvements in Speeders for Bicycles, of which the following is aspecification.

My invention has for its object to ohviate some of the strains and reduce the effects of some of the forces tending to throw the wheel of a bicycle out of balance; and to this end my invention consists in 'an attachment for a wheel of a bicycle, as fully set forth hereinafter and as illustrated in the accompanying drawings, in Which- Figure 1 is an elevation of a bicycle with Fig. 2 is al longitudinal section of the device. Fig. 3 is a transverse section.

My improved attachment consists of two blocks A A', o f lead or other heavy material and of any suitable shape,preferably of such a form, however, that when they are put together face to face they will present an eggshaped outline, and in the fiat face of each block is a longitudin al groove y of such a size that when the blocks are brought together the said grooves will receive one of the spokes of a bicycle. In connection with these blocks is used a clamp B of suitable construction, as shown consisting of a single strip of metal bent round to fit a recess 6 in the block and to form ears 9 9 at the ends, through which ears extends a bolt 7, provided With a nut 8.

In adj usting and securing the device to a bicycle the twoblocks A A' are placed upon one of the spokes thereof at any suitable point, so that the said spoke will lie inthe Serial No. 682,195. (No model.)

grooves y y, and the clamp B is then slipped over the blocks until it entersthe recess 6, when the nut is turned to tighten the bolt, bind the clamp in the recess 6, and bring the two blocks A A' firmly against the spoko, binding the device immovably thereto.

The above-described device may be attached to any spoke and in any desired position, the adjustment being such as will best secure the effects of the momentum of the heavyweight in overcoming the strainof the chain and a other forces tending to disarrange the proper relation of the wheel to the frame of the vehicle in running.

While I have described a certain form of blocks and clamp, it will be evdent that the forms and proportions of the blocks or mode of clamping may be changed without materially departing from the nature of my invention.

I Without limiting myself to the precise construction and arrangement of parts described,

WILLIAM READING GULICK.
